Calculating electron-phonon coupling and MacMillan Tc

Hi, I try to calculate Tc of Be2Li as in the article http://link.aps.org/doi/10.1103/PhysRevB.78.172501 for 20x20x20 k-mesh and 2x2x2, 4x4x4, 5x5x5 qpt subgrid. I can get the nearly same phonon band structure but the calculated Tc is very low(0.315 K, lambda=0.53 for 5x5x5 and mustar=0.1 and decreas...

Re: How to calculate the enthalpy under different pressure

thank you for reply,

that is what i did yesterday but i though that could be an output gives for enthalpy. but i calculated greping volumes and pressures and Total energies from the outputs with the general enthalpy formula above.

How to calculate the enthalpy under different pressure

I need to calculate enthalpy for a system under various pressure between 0 to 600Gpa. I can optimize the systems under different pressures, but how can i calculate/get enthalpy of each system to plot enthalpy-pressure relation.

is it available at somewhere in output file of the optimizatim?

thanks

AbinitBandStructureMaker computes wrong # of valence elctrn

does anyone have problem with the AbinitBandStructureMaker.py that comes with the latest version of Abinit 6.8.1? It calculates the wrong number of valence electrons for my system and i just fixed it by changing the line #781 as follows
nion.append(float(ctrl.filedata[i+3].split()[1]))
